Signal terminations are required for the CK and ADDR_CTRL net class signals. On-device terminations (ODTs) are required on the DQS[x] and DQ[x] net class signals. Detailed termination specifications are covered in the routing rules in the following sections.
Figure 7-48 provides an example DDR3 schematic with a single 16-bit DDR3 memory device that does not have VTT termination on the address and control signals. A typical DDR3 point-to-point topology may provide acceptable signal integrity without VTT termination. System performance should be verified by performing signal integrity analysis using specific PCB design details before implementing this topology.
